Writing a quadratic from standard form to vertex form by completing square

The video tutorial explains how to convert quadratic equations from standard form to vertex form. It begins by discussing the importance of finding the axis of symmetry and vertex. The tutorial then delves into the concept of perfect square trinomials and how they relate to binomial squares. The process of creating a perfect square trinomial is detailed, including the use of the B/2 method. Finally, the video demonstrates the conversion to vertex form and discusses the resulting graph's properties, such as axis symmetry and range.
